Trap spacing: 0.5

Sampling comments: "We installed cameras during July and August 2013... cameras operated until October 2014... Camera locations were determined through a spatially balanced design generated via the Reversed Randomized Quadrant-Recursive Raster (RRQRR) algorithm... Sampling sites were > 500 meters apart except for two pairs of cameras, where one camera per pair was censored... We programmed camera traps to trigger by movement and to capture a time-lapse image every hour for the first 12-months of sampling. We increased the rate of time-lapse images to every 30 minutes for the last 3-months of sampling after noting the available space on the memory cards... our 54 cameras operated for 19,199 camera trap days and captured ~825,000 photos"
I presume there were 27 cameras per field area (9599.5 trap days each); the triggering period was 12/15 months, so there were 7679.6 triggered trap days and 1919.9 time-lapse trap days per field area"
